Harlequin poison frog

Oophaga histrionica

需要看医生不要触摸很少致命，但如果有人碰了或吃了它，要去看医生。

皮肤里有毒吃：昆虫碰了或吃了有毒，不注射毒液

The harlequin poison frog is a small, brightly marked frog that lives on the forest floor of western Colombia. Its skin carries strong toxins, so it is one of the poison dart frogs that should never be handled. It is now critically endangered because its rainforest home is being destroyed.1

有毒还是有毒液？有毒液的动物通过咬或蜇注入毒液。有毒的动物是碰了或吃了会受害。这一种是碰了或吃了有害的。

怎样认出它

Background colour ranges from light to dark brown.1
Usually has a vivid, bright spot on its back.1
Small, with an average snout-to-vent length of about 3.3 cm.1
Active on the forest floor, feeding on the ground after sunrise and hiding under leaf litter or on fallen logs by 16:00.1

常被误认为： Some frogs that were once classed as this species were separated into new species in 2018: Oophaga anchicayensis, Oophaga andresi and Oophaga solanensis.1

毒力

皮肤里有毒

它的皮肤有毒。摸、舔或吃都很危险。

它的毒会造成什么？

The frog produces histrionicotoxins, which are cardiotoxins, meaning they affect the heart. These compounds act as potent blockers of nicotinic acetylcholine receptors, the sites that receive nerve signals at muscle and nerve junctions. They also affect sodium and potassium channels, though much less strongly.1

它对人有多危险？

对人的危险: 严重如果有人碰了或吃了它，要去看医生。死亡非常罕见。

The frog's toxins can be dangerous. Wild-caught frogs may be toxic and dangerous to handle, and they often have a much higher fatality rate in captivity.1

如果有人碰了或吃了它

如果有人碰了它：好好洗手，不要碰眼睛或嘴巴。如果孩子或宠物舔了或吃了它：打电话给中毒急救中心或急救电话。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果你碰了或吃了它：不要揉眼睛或嘴巴，洗手并就医。

它不是冲着你来的。它的毒只是为了不被吃掉。更多安全知识

值得了解

事实

The tadpoles cannot feed on their own. They are obligate egg-feeders and will starve without the unfertilised eggs their mother provides.1

A parent carries the tadpoles to tiny water pools, often found in the axil of a bromeliad plant, where they develop.1

Histrionicotoxins are hard to make in a lab. Synthesising them has been the subject of many different attempts.1

Harlequin poison frogs are among the most difficult poison dart frogs to raise in captivity.1

Adults are active on the ground during the day and retreat to refuge by mid-afternoon.1
